I have been using Class 4 SD card for my HD2 EU but was haiving many issues with DataOnExt and NativeSD Versions.I want to purchase a new 16GB SD Card for my phone but confused with a normal Class 10 card and UHS-1 Card.

I have researched a lot and many people say that UHS-1 cards dont work properly with HD2.I looked for two UHS-1 cards.

My old class 4 sd card worked fine with tytung's ICS rom but with Kitkat not. So I decided to buy some card for testing. I was thinking about class 10 and UHS-I and finally I bought UHS-I. Works quite fast - see attachement. I'm really curious how fast the hd2 with class 10 is?

I'm glad to hear that you're currently experiencing success with your UHS-1 SD-card, however, I recommend you back up everything and keep them current, because cards of this speed are known to be problematic with the HD2. If you begin experiencing random reboots or crashes in apps that were stable before you'll know that this card is the reason. I speak from personal experience. The issue is caused due to timing incompatibilities with the controller chip on the HD2, which came out several years before the UHS-1 standard was created. Class-10 cards generally seem to work without issues, however, UHS-1 cards tend to be unstable.

I wish you much luck and success with this combination, but as mentioned, if you begin having mysterious stability issues please don't blame them on Tytung or his ROMs and post requesting support, because the cause has already been pointed out to you.
